NOW, THEREFORE, for good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties hereto agree as follows:

SECTION 1. Waiver; Limitations.

The Cardinal Entities have advised the Agent that prior to the date hereof (i) certain Receivables included in the calculation of the Net Receivables Balance and sold to the Seller under the Receivables Sale Agreement were originated by the Approved Sub-Originators (as defined in Section 2 below) rather than by the Originators, (ii) the sales of such Receivables by such Approved Sub-Originators to the Originators were not memorialized by written sale agreements, (iii) UCC financing statements may not have been filed against such Approved Sub-Originators to perfect the interests of the Originators, Griffin, the Seller or the Agent (on behalf of the Purchasers) in such Receivables or the Related Security therefor and (iv) due to the circumstances described in clauses (i) through (iii) above, such Receivables did not constitute Eligible Receivables. The circumstances described above resulted in breaches of various representations, warranties and covenants of the Cardinal Entities under the Transaction Documents and constitute continuing Amortization Events under the Receivables Purchase Agreement (such breaches and Amortization Events, solely to the extent arising from the circumstances described in the first sentence of this Section 1, the “Subject Events”). The Cardinal Entities have requested the waivers described in clause (a) below.

(ii) each of the Agent and the Seller hereby waives the occurrence of the Subject Events under the Receivables Sale Agreement;

(iii) each of the Agent and the Seller hereby waives the occurrence of the Subject Events under the Performance Guaranty; and

(iv) each of the Agent, Seller and Griffin hereby waives the occurrence of the Subject Events under the Griffin RPAs.

Each of the parties hereto consents to the waivers granted pursuant to this clause (a). Each of the parties granting a waiver pursuant to clause (i), (ii), (iii) or (iv) above, as applicable, is hereinafter referred to as a “Waiving Party”.

(b) General Limitations. Notwithstanding anything to the contrary herein or in the Transaction Documents, by executing this Amendment, none of the Waiving Parties is now waiving, nor have any of them agreed to waive in the future, the breach of (or any rights and remedies related to the breach of) any provisions of any Transaction Document, other than as expressly set forth in clause (a) above. Without limiting the generality of the foregoing, none of the Waiving Parties is now waiving, nor have any of them agreed to waive in the future, any Termination Event (as defined under the Receivables Sale Agreement) or Amortization Event, in either case, occurring after the date hereof. For the avoidance of doubt, no Waiving Party is hereby waiving or agreeing to waive in the future any event or circumstance similar to the Subject Events that occurs after giving effect to this Amendment or any of their respective rights or remedies in respect thereof under the Transaction Documents, applicable law or otherwise.

(c) No Waiver of Indemnification, Etc.
